# Can solving quadratics using the formula come up in the non-calculator paper?

Or does it only come up in the calculator paper?

Thanks. :)

Yes it can. However all they will ask u is to keep ur answer in a surd form or say something like solve using the quadratics where   (2 + [k x root b]  )  / 6  where k and b are constants to be found etc ...

Okay. And if you don't mind, how do you know when to use the quadratic formula?

The question will ask you solve a quadratic equation. and then what I do is try see if I can solve it using factorising. If this takes too long and I can't figure out a way to do this, I use the formula as it will always work...but some of my friends skip the factorising bit and solve all quadratic equations with the formula as they think its easier and is bound to work! :)

well it culd say how i said it, wot i mean is the example i gave u or if u try to factorize it wont but it will be safer if u go for the formula and make sure u are quik with it as well!!!

no it cant, well in aqa it will only come up in calculator exam to use the actual quadratic formula although you may be asked to solve quadratic equations by factoring although they will be simpler than ones needed to use a calculator for!

hope it makes sense!
